Abstract

Zur möglichst exakten Drehzahlbestimmung einer Welle (1), an der umlaufend eine Anzahl von abtastbaren Signalgebern (SG) in äquidistanten Geberpositionen (n) angeordnet sind, werden Zeitintervall-Kennwerte (T(n)) der von aufeinander folgenden Signalgebern (SG) abgegebenen Signalimpulse (SI) ermittelt, wobei einer Geberposition (n) im Bereich einer Geberlücke (GL) der für einen um einen vorgegebenen Winkel (α) periodisch versetzt angeordnete Geberposition (n) ermittelte Kennwert (T(n)) zugeordnet wird. Eine Vorrichtung zur Durchführung des Verfahrens umfasst eine Rechnereinheit (8) mit einem Zähler- und Timermodul (7,9) und mit einem Auswertemodul (11), dessen selbstlernender Algorithmus jeder Geberposition (n) im Bereich der Geberlücke (GL) einen während einer winkelversetzten Lernphase ermittelten Kennwert (T(n)) zuordnet.

Figure 00000001
For the most accurate determination of the speed of a shaft (1) on which a number of scannable signal generators (SG) in equidistant encoder positions (n) are arranged circumferentially, time interval characteristics (T (n)) of the signal pulses emitted by successive signal generators (SG) (SI) is determined, wherein a sensor position (s) in the range of a sensor gap (GL) of the for a by a predetermined angle (α) periodically offset arranged encoder position (n) determined characteristic value (T (n)) is assigned. An apparatus for carrying out the method comprises a computer unit (8) with a counter and timer module (7, 9) and with an evaluation module (11), whose self-learning algorithm of each encoder position (s) in the area of the encoder gap (GL) one during an angular offset Learning phase (T (n)).
